    • PROBLEM TO BE SOLVED: To provide a flaw detecting liquid supply device which appropriately supplies liquid for a flaw detection in a performance of an ultrasonic flaw inspection, and a vehicle including the flaw detecting liquid supply device.SOLUTION: Flaw detection water in a tank 11 flows to an electromagnetic valve 144 of a flaw detecting liquid supply device 14 through an upstream water piping portion 131. Because the electromagnetic valve 144 opens and closes based on an electric pulse drive signal, the flaw detection water intermittently drops into a reservoir tank 141 to be intermittently supplied into the reservoir tank 141. The flaw detection water stored in the reservoir tank 141 is flowed to a discharge portion through a downstream water piping portion 132. Because the flaw detection water is controlled to be constant in the reservoir tank 141, the flaw detection water is constantly supplied from the reservoir tank 141 to the discharge portion and discharged continuously.
    • 要解决的问题:提供一种在执行超声波探伤的过程中适当地供应用于探伤的液体的探伤液供给装置,以及包括该探伤液供给装置的车辆。解决方案:罐11中的探伤水 通过上游供水管道部分131流向探伤液供给装置14的电磁阀144.由于电磁阀144基于电脉冲驱动信号而打开和关闭,所以探伤水间歇地落入储液罐141至 间歇地供给到储存罐141中。储存在储存箱141中的缺陷检测水通过下游水管道部132流向排出部。由于在储存罐141中将缺陷检测水控制为恒定, 缺水检测水从储存罐141不间断地供给到排出部,并连续排出。

    • PROBLEM TO BE SOLVED: To provide an apparatus for detecting metal fatigue of the surface of a rail and capable of evaluating metal fatigue by detecting the occurrence of minute cracks, in a state immediately prior to the occurrence of flaws.
      SOLUTION: A surface wave probe moves along a rail, as being in contact with the surface of the rail; generates surface waves toward the surface of the rail on the basis of transmission pulse signals; receives reflected waves reflected by a reflection source which can be present in the surface of the rail; and converts them into reception signals. Reception level signals of reflected waves are integrated at the surface wave probe, over a plurality of times of transmissions and receptions in a prescribed section, corresponding to an integrated value and a moved position to each other and to record them. Metal fatigue can be evaluated, on the basis of the integrated value.
